UNITED STATES PATENT OFFICE.

MARMADUKE L. WHITEHEAD, OF CHAPANOKE, NORTH CAROLINA.

CATTLE-GUARD.

SPECIFICATION forming part of Letters Patent No. 671,361, dated April 2,1901.

Application led January 10, 1901. Serial No. 42,784. (No model.)

To all whom it may concern.-

Be it known that I, MARMADUKE L. WHITE- HEAD, a citizen of the UnitedStates, residing at Chapanoke, in the county of Perquimans and State ofNorth Carolina, have invented certain new and useful Improvements inCattle-Guards; and I do hereby declare the fol-` lowing to be a full,clear, and exact4 description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to means for preventing stock-such as horses,cows, and swine-from crossing a railroad-track or passing from oneinelosure to another through the gap in the fence occasioned by thetracks traversing a farm or crossing a road.

The essential feature of the invention is a series of toothed or spikedrollers disposed in parallel relation to one another and located betweenand at the sides of the rails, the rollers preventing an animal fromobtaining a sure footing and the-teeth or spikes iniicting punishment,the two actions being simultaneous, thereby being effective as a barrierto prevent stock from trespassing upon anothers land or passing beyondgiven bounds.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand drawings hereto attached.

While the essential and characteristic features of the invention arenecessarily susceptible of modification, still the preferred embodimentof the invention is illustrated in the accompanying drawings, in which-Figure 1 is a plan view of a cattle-guard embodying the invention. Fig.2is a section on the line X X of Fig. '1. Fig. 3 isa section on the lineY Y of Fig. l. Fig. 4 is a perspective view of the end portion of one ofthe V-shaped bars alternating with the toothed rollers and a part of theadjacent plate.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The guard comprises a series of toothed or spiked rollers 1, arranged inparallel relation to one another and located between and at the sides ofthe rails. The toothed rollers of each series are spaced apart and aremounted in any substantial manner, so as to tu rn freely upon theapplication of any weight or pressure to a side portion thereof. Theteeth or spikes are sharpened so as to prick the animal and inflictpunishment sufficient to prevent its advance after making an attempt tocross the track to pass from one inelosure to another along the track.The rollers may be of any length and diameter and may be constructedeither of wood or metal. The middle rollers are longer than the rollersat the sides of the track and terminate close to the rails, so as toleave a minimum amount of space for an animal to obtain a footing whenattempting to walk the rail, so as to clear the guard or interposedbarrier. While the toothed rollers may be mounted in any convenient andsubstantial way, it is preferred to provide longitudinal strips orplates 2, having openings in transverse alinement to receive thejournals of the rollers. A pair of strips or plates 2 is had foreachseries of rollers and the plates are connected intermediate of therollers preferably by means of transverse bars 3, having their oppositesides sloping upwardly to an edge, so as to prevent an animal fromobtaining proper footing thereon. The bars 3 and toothed rollers l arealternately arranged, and ample space is provided between their opposingsides to admit of the free passage of the foot of an animal, so that inthe event of the foot passing between a roller and the adjacent bar itcan be readily extracted without injury other than occasioned by thepricking or punishment iniiicted by the teeth or spurs of the roller.The bars 3 are preferably formed of plates of metal folded intermediateof their longitudinal edges into approximately V shape, the ends beingoutwardly flanged, as shown at 4:, and pierced to receive fastenings 5,by means of which they are secured to the strips or plates 2. By havingthe strips or plates 2 connected at intervals by means of the bars 3they may be exceedingly light and comparatively thin metal may be usedin their IOO formation. When the guard is placed in position, it issecured by firm attachment either to the ties or sleepers, or to both.

Having thus described the invention, what is claimed as new is- 1. Acattle-guard comprising a series of rollers spaced apart, and acorresponding-series of transverse bars located in the spaces formedbetween the rollers and having their sides upwardly sloping to an edge,substantially as set forth.

2. A cattle-guard comprising toothed or spiked rollers arranged parallelwith one another and spaced apart, and V-shaped bars located in thespaces formed between adjacent rollers, substantially as set forth. J

3. In a cattle-guard, longitudinal strips, transverse bars connectingthe strips at in- MARMADUKE ll. WHITEHEAD. [Ls] Witnesses:
